A component for sand-fixing, tree-planting, rain-collecting, water-retaining and sand-controlling

Abstract

The invention discloses a sand-fixation tree-planting rain-collecting water-conservation desertification-control component and belongs to the technical field of desertification-control facilities. Theand-fixation tree-planting rain-collecting water-conservation desertification-control component comprises a water storage barrel body, a fixed rod and arc-shaped position-limiting plates, the fixed rod comprises an outer pipe located at the internal central axis position of the water storage barrel body and an inner pipe arranged inside the outer pipe, the top end of the outer pipe is fixedly provided with a rain receiving tank matched with an upper end opening of the water storage barrel body, the bottom of the rain receiving tank communicates with the outer pipe, the lower end of the outerpipe penetrates through a cover plate, water absorption fillers and the bottom of the water storage barrel body in sequence, the outer pipe is provided with water through holes communicating with a water storage cavity in a distributed manner, the length of the inner pipe is larger than that of the outer pipe, the lower end of the inner pipe is provided with at least three stabilizing claws whichare distributed at equal intervals in a horizontal circumference surface, elastic parts are connected between the stabilizing claws and the inner pipe, dragging ropes are connected between the free ends of the stabilizing claws and the inner wall of the outer pipe, in an initial state, the stabilizing claws are drawn inside the outer pipe, and the dragging ropes are wound on the inner pipe and arein a slack state. The sand-fixation tree-planting rain-collecting water-conservation desertification-control component is relatively labor-saving in installation, and fixing mechanisms can be reused;and the sand-fixation tree-planting rain-collecting water-conservation desertification-control component can be adapted to growth of trees and is good in application effect.

Description

technical field [0001] The invention relates to the technical field of desert control facilities, in particular to a component for sand-fixing, tree-planting, rain-collecting, water-retaining and sand-controlling. Background technique [0002] Desert ecology is deteriorating, and dust and sandstorms are frequent, affecting social life and endangering economic development. With the trend of warming and drying the global climate, desert control is becoming more and more urgent. The arid sandy area has a dry climate, little rainfall, strong evaporation, strong winds, loose soil, and flowing sand. At present, people mainly use barriers to fix sand and plant trees and grass to curb the desertification process, and some results have been achieved. However, the desert area is vast and the natural conditions are complex. Except for a few areas that rely on abundant water resources and use engineering irrigation to make vegetation reconstruction better, in places where irrigation con...
